So, lets see what Saturn can do in 5th house without any conjunction or aspect from any other planet. 1st lets see what these 2 things represent --

Saturn is all that which we don't like in our life. Saturn is delay, frustration, restriction, limitation and anxiety. It is hard-work and labor. It is people of authority, like boss at your work place or father-figure at home. Saturn is Master and Servant both (depends on who uses Saturn in what way). Saturn is our Karmic debt from life. Saturn is the things we didn't treat too well in our past life. Saturn is our challenges and lessons of life. Saturn is old-age, teeth in human body, diseases, transformation etc. Saturn is discipline, organisation, structure, government, law & order etc.

5th house represents Creativity, Romance, Happiness, Hobbies, Children, Innovation, Sports, Movies, Stock Trading, Gambling and Betting, Risk Taking Ability, Education, Ancient Texts etc.

So, now Saturn is in 5th house. Here, it can create obstacles and delays in Higher Education of person. Fun and Love Life becomes a kind of responsibility or burden. Actually, like any other house, in this house also if you want to receive anything from Saturn, you have to show discipline, perseverance and realistic approach towards those things. Like, in education, you need to be disciplined and persevered for your education. If you are thinking that you will study in last 2 months of exams and get the degree, then you are here for some hard lessons. Likewise, in love life, you have to be have a very realistic approach for your romance. It can't be a dream love story because Saturn then will show the reality of things, which would be rather bitter. It is better option for these people to go for arranged marriage then love marriage because love partners are not going to stay. Actually, as Saturn represents delays and long duration, it gives a very long love relationship and then it breaks. Just to teach us some life-long lessons. In 5th house, it delays the child birth till 30s, but as always Saturn only delays, it never denies.

Saturn's 3rd aspect goes to 7th house of Marriage and it is better for individual to wait for marriage till 30s. Only then person will be able to understand the realistic and responsibility side of marriage.

Saturn's next aspect goes to the 11th house of hopes, wishes, desires etc. So, their desires will actually be fulfilled in their 30s. Till then it is learning time.

Saturn's last aspect goes to 2nd house of family and wealth. So, these people always feel that they have not got proper supportive environment in family. They may be speaking very less and only when it matters. It can also show that person had to take up responsibility of earning wealth very early in life.
